Re: I get this string often when I use mods I probably ripped unsuccessfully...

@netherkrow It's not that they become more corrupt - it's that you can't see in them or find their contents in a search. So you can end up with two copies of the same file, with mods/CC that are outdated because of a game patch but you can't delete just that mod/CC, and with mods that you end up with earlier and later versions of. And that comes with no benefit to you as a player, because merging CC files doesn't improve anything in-game. And older merged files you find somewhere online are more likely to contain content that's already outdated/broken.

Of note, no CC or mods is downloadable from the Gallery for Sims 4, only from outside sites.
